All of our support is phone-based and uses remote assistance tools when necessary. Most of our twenty-five agents are still on XP or Vista at home, and we'll probably only have it on our work machines a month before the users do. They need training from basic differences up through providing detailed troubleshooting assistance. Of course our budget is pretty limited, and I've been tasked with finding training materials we can use to get the desk up to speed.

What are good sources for training beyond what we can get for free from Microsoft, which seems mostly targeted at the end-user. I'm looking for both computer-based materials and "train-the-trainer" stuff I can use to prepare for my classroom.
